TRAVERSE-RING.

Patented Aug. 10, 1909.

To all whom it may concern:

Be it known that I, THOMAS D. STONE, a citizen of the United States,residing at Wallingford, county of New Haven, State of Connecticut, haveinvented certain new and useful Improvements in Traverse-Rings, of whichthe following is a full, clear, and exact description.

My invention relates to improvements in so-called traverse rings forportieres, curtains and the like.

The object is to improve and simplify the constructlon.

In the drawings, Figure 1 is a side elevation, partly in section, of atraverse ring constructed to embody my invention. Fig. 2 is aperspective view illustrating a portion of the ring in section on theline X-X Fig. 1. Figs. 3 and 4 are detail views.

This invention relates particularly to that type of traverse ringsemployin anti-friction bearings, and in this particu ar instance,comprises the two main sections 12, be-

tween the ends of which, when assembled,

are located anti-friction rolls 3-3. The main sections 12 are each oftubular form. The anti-friction devices in the particular form areformed by uniting two cupped Each of these rolls 3 is mountedupon atubular bearing 4. At each end of the tubular bearing is a head oranchor block 5. Each of the heads 5 is arranged to make a driving fitupon the tube 4, or may be secured thereon in any other desired manner,so as to firmly connect the parts and furnish the proper space for therolls 3 between said heads. Each head is preferably provided with anannular shoulder 5;

6 is a reinforcing core member, which may be conveniently formed of aheavy stock of wire, curved to the contour of the finished.

traverse ring and arranged to stand within the same (as best seen inFig. 1), said core passing loosely through the pasage in each tube 4.Each extremity of the core 6 projects well into the section 1 of thering. To prevent the displacement of the core, offsets or heads 66 maybe provided to stand between the two heads 5-5, as shown in Fig. 1.

Each end of each tubular section 1,2 is connected with a head 5,theshoulder 5 thereon furnishing an abutment, to the rear of which themetal of the tubular section maybe crimped in so as to preventseparation.

In assembling, the core 6 would first be placed in the tubular section2, the anti-friction devices with the heads 5 would then be applied toeach end of said section 2 and firmly secured thereto. The ends of thecore 6 would then be exposed. The section 1 would then be applied, beingslipped easily over the ends of said core. The ends of the section 1 arethen slid over the outer ends of heads 55 and crimped down behind theshoulders 5 so as to tie the parts together and complete the article asshown in Fig. 1.

Since the ring as constituted is made up of two sections, it is obviousthat the core 6 performs the very useful function of reinforcing thering, whereby undue twisting is prevented. In the event the ring istwisted, the extremities of the core would very quickly engage the sideof the section 1 (see dotted lines, Fig. 2) thus resisting any furthertwist. Where the flexibility of the metal itself will permit a moderateamount of twist, for example, such as unlimited by the core, any suchtwist as would tend to weaken the fastenings would be prevented by thepresence of the core. This furnishes a very simple, inexpensive andeffective means for providing in this type of ring unusual strength.

What I claim is:

1. A traverse ring having a tubular body divided at one side, means forconnecting the divided ends of said tube, an anti-friction devicecarried by said means, said connecting means having a passage, and areinforcing core passing through said passage, the ends of said coreprojecting well into the tubular body.

A traverse ring having a tubular body divided at one side, means forconnecting the divided ends of said tube, an anti-friction devicecarried by said means, said connecting 'means having a passage, and areinforcing core passing through said passage, the ends of said coreprojecting well into the tubular body, said core being formed of wirecurved to the contour of said ring.
